TOBACCO PIPE CLEANING DEVICE John W. Bentley, Chicago, Ill.

Application July 2'7, 1946, Serial No. 686,792

12 Claims.

My invention relates to tobacco pipe cleaning devices, and consists of a simple instrumentality made of resilient material, such as rubber, or cork, and which is used in connection with water, or air'pressure means, causing the fluids to course through a smokers pipe to eifectuate the cleaning operation.

An important object of my invention is to provide a device of the aforementioned character, which consists of a plug element made of resilient material, and having therein means for connection to the outlet of water pressure, or air pressure means, and. means for receiving the pipe stem of a tobacco pipe.

2. device of the aforementioned character which is adapted to establish 'a leak-proof or sealed communication when intermediately positioned between air, or water, pressure means, and pipe stem means.

A further object of my invention is to provide a device of the aforementioned character made of resilient material which is adapted to establish communication between Water pressure means -'or air pressure means, and the cavity in the pipe bowl.

A further object of my invention is to provide a plug-type of intermediate seal connection, which consists of a substantially small peripherally cylindrical portion having a frusto-conical portion on one side of the said peripheral portion, and a frusto-conical portion on the opposite side of the said peripheral portion.

A further object of my invention is to provide a slightly modified form of seal plug means of the aforementioned character, which is provided with a peripherally cylindrical portion, a frusto-conical portion on one side of the said peripherally cylindrical portion, and a spherical portion on the opposite side of the said frustoconical portion.

A further object of my invention is to provide a device of the aforementioned character which consists of a peripherally cylindrical portion, and two spherical portions contiguous to each side of the said peripherally cylindrical portion.

A further object of my invention is to provide a pipe cleaning seal plug of the aforementioned character, which is simple in construction, practical and efiicient in its operation, I efiectively cleaning a smokers pipe rather expediently, and. an article which is of such simple elemental construction as to warrant manu- Another object of my invention is to provide FFICE 2 iacture thereof economically in quantity producion.

Other features, objects, and ancillary advantages inherent in my invention will become apparent from an examination of the accompanying drawings, having further reference thereto in the ensuing description, wherein like symbols are used to designate like parts, and. in which:

Fig. 1 is a front view with certain portions indicated in cross-section, clearly elucidating the structure and application of one form of my invention.

Fig. -2 is an end view of Fig. 1, with certain portions broken away and shown in section to more clearly depict the structural relationship of the parts.

Fig. 3 is a plan View of one form of my invention.

Fig. 4 is a front View of Fig. 3.

Fig. 5 is a bottom view of Fig. 4.

Fig. 6 is a cross-sectional view taken, substantially, on the line 6-6 of Fig. 5.

Fig. 7 is a transverse cross-sectional view, taken substantially, on the line 'l-l of Fig. 5.

Fig. 8 is a plan view of a slightly modified form of my invention.

Fig. 9 is a cross-sectional view of Fig. 8.

Fig. 10 is a sectional view indicating another method of using the various forms of my invention.

Fig. 11 is a View similar to Fig. 10 showing the form of my invention used in Fig. 10, it being used in inverted position to effectuate the same results.

Fig. 12 is across-sectional View similar to Fig. 1-0 showing air pressure means being used, as distinguished from the water pressure means used in Figs. 10 and 11.

Referring now to the various views, l3 illustrates the nozzle of a water tap or other means of liquid pressure, having an outlet bore [4 therein, and showing one form of my invention generallydesignated l5, assembled. in connection with a tobacco pipe generally designated 2 i, the view depicting the process-of actually cleaning the pipe by means of ingress of the water pressure through the stem conduit, and egress of the liquid and the material being cleaned from the pipe from the cavity 24 in the bowl 23 of the pipe 2|.

My invention, generally designated I5, in this particular instance, consists of a peripherally cylindrical portion I8, of shallow dimension, having contiguous to the top thereof, a frusto-conical section 16, and contiguous to the bottom thereof another frusto-conical section H. The

bottom portion is provided with an elongated slot 20 to fit snugly over a pipe stem 22, which permits the liquid from the tap I3 to fiow therethrough, as well as through the conduit 33, or the passage 33, in the pipe stem 22.

Figs. 3, 4 and 5 show the detail structure of one form of my invention, namely, the particular form containing the oppositely disposed frusto-conical section.

Figs. 6 and 7 show another form of my invention, wherein the same is generally designated 25, and diifers from the form illustrated in Figs. 3, 4 and 6 only in the structure of the portion contiguous to the bottom of the peripherally cylindrical portion I8, which instead of being a frusto-conical portion, in this particular instance is a spherical portion designated 21, the top portion thereof being frusto-conical, and designated 26 being similar to the frusto-conical section I6 of the form illustrated in Figs. 3, 4 and 5.

In Fig. 9, I show a slightly modified form of my invention, which is made up to have contiguous to the peripherally cylindrical portion I8 two spherical sections, one at the top designated 29, and one at the bottom designated 30, this form of my invention being generally designated 28. All forms are provided with the stem receiving opening 20, and the passage-Way or conical bore I 9 for establishing communication between the source of pressure and the tobacco pipe to be cleaned.

In Figs. 10 and 11, I show that form of my invention, generally designated 25 being used in connection with liquid pressure means from the tap, and the difference between Figs. 10 and 11 is, primarily, in the showing of the universal method or manner in which all the forms of my invention 25, 28 and I5 may be used, 1. e., either in upright, or inverted positions as indicated by Figs. 10 and 11.

Fig. 12 shows the use of my device in connec tion with cleaning a smokers pipe, when the pressure is supplied by an air hose 3|, having a valve head 32, which will seal about the opening of the bore I9, and thus cause the air pressure to flow through the pipe.

In cleaning the pipe, as illustrated in Figs. 1 and 2, the contaminated liquid is caused to flow from the stem, through the pipe, and exit through the bowl cavity 24.

In Figs. 10, 11 and 12, the reverse procedure is indicated, in that either the fluid or the liquid pressure is utilized between the pipe in the reverse operation, that is, namely, by causing either the air pressure, or the liquid pressure to flow from the bowl cavity 24 through the pipe, and exit at the forward portion of the pipe stem passing through the passage or conduit 33.

All of the forms of my invention may be made of rubber, or similar resilient material, either of natural or synthetic type, or cork, or similar material; however, I have found that a resilient, or rubber-like material is the most ideal, especially in view of the fact that the cavity, or slotted portion 20, of necessity, must be receptive to different widths of pipe tips.

I believe, I have herein disclosed, and described, rather succinctly, the structure, the application, and use of various slightly modified forms of my invention, and inasmuch as the same are susceptible of modifications, improvements, and alterations, I hereby reserve the right to all such modifications, alterations, and improvements coming within the scope and spirit of my invention, as

well as any of those that are impliably suggested or embraced in the accompanying drawings, and also all those that fall within the purview of the foregoing description; my invention to be limited only by the subjoined claims.
